A case of unresectable multiple liver metastases of colorectal cancer in which ALTA (ZION®) used to control internal hemorrhoidal bleeding, enabled administration of bevacizumab

Our patient was a 58-year-old woman with internal bleeding hemorrhoids who was undergoing FOLFOX6 treatment for unresectable multiple hepatic metastases of colorectal cancer. Response evaluation after 6 courses showed stable disease (SD), but side effects necessitated a change in regimen. Hemorrhoidal bleeding had also increased, and hemorrhoid-sclerosing therapy with ALTA (ZION®) injections was administered. Because no bleeding was evident after treatment and the clinical course was uneventful, chemotherapy with bevacizumab was restarted. No hemorrhoidal bleeding occurred after bevacizumab administration, and the patient is currently continuing chemotherapy. In patients with advanced cancer who have bleeding internal hemorrhoids that cannot be controlled with conservative treatment, hemorrhoid-sclerosing therapy using ALTA appears to offer an effective treatment variation that enables the use of bevacizumab in cases with limited available therapeutic regimen options.
